Teenage girl detained in St. Petersburg for arson on police vehicles

A teenage girl was detained in St. Petersburg on suspicion of setting two police cars on fire outside a station on Marata Street, per a source cited by Fontanka. The incident appears to be a localized criminal act; no broader pattern or political motive is confirmed. It matters as a law-enforcement and public-safety event in Russia, but has no immediate market or geopolitical significance.
